May 12, sponsored by the China Automotive Technology and Research Center (hereinafter referred to as the Automobile Center), the Automobile Center Data Resource Center contractor,The European Automobile Manufacturers Association, the International Iron and Steel Institute, the International Chemical Manufacturers Association, Japan Auto Parts Industries Association and supported by "2015 (Fourth) International Symposium on vehicle materials technology" held in Beijing.The meeting of "materials technology innovation" as its theme, focusing macroeconomic policy trends, key aspects of materials technology, automotive interior air quality and hazardous substances carried out in-depth discussion and exchanges.

Strict environmental clearance is the only way for the sustainable development of car prices

In the new normal economy, the auto industry how to get out of a green healthy road cycling?Deputy Director from the Ministry of Energy and Resources Utilization Division of Workers   Bi Junsheng at the meeting that,Sustainable development of China's auto industry severely restrict environmental pollution, energy shortages, traffic congestion and other factors,In the automotive industry, green low-carbon development cycle Ministry carried out work includes actively promote eco-design, to carry toxic and hazardous materials substitution process to strengthen pollution control, and vigorously promote the popularization and application of new energy vehicles, strengthen passenger car fuel consumption management and other aspects of .Among them, in strengthening the process of pollution control, regularly organized by the Ministry issued the "green auto industry development report"The use of hazardous substances released cars recyclable utilization and other information, automobile manufacturers for system construction, green supply chain management to summarize the assessment,To promote the automobile industry production, consumption patterns shift to a green low-carbon energy security, improve the international competitiveness of enterprises related products.

Build a green supply chain, accelerate the construction of resource-saving and environment-friendly guide procurement, production, marketing, recycling and logistics system,Is currently the automotive industry and many auto-related companies are actively promoting the work.Zhang Jianwei, deputy director of the Automobile Center, said automotive products is a complicated systematic project, including a wide range of different properties of hundreds of materials, a lot of the core technology breakthrough car, causes the material.He noted that in recent years, about the car of hazardous substances, air quality inside the car's fuel consumption, emissions and product eco-design and other aspects of policies and regulations promulgated to implement the standard,How auto focus from a height, in the product design, production process fully implement the concept of environmental protection, strict environmental quality, has become a business to meet the national regulatory requirements, social responsibility, the only way to achieve sustainable development.

Automotive lightweight is an important direction

Lift the automotive materials technology, always the lightweight.Senior Associate of the International Council on Clean Transportation (ICCT) JohnGerman believes that the next generation of automotive technology, mainly in transmission direction,One very important part of that comes from the weight loss, which is lightweight, material aspects of product design and factors that will be half and half.For example, you can reduce the use of the power system and reduce costs. Especially for the use of new energy technologies, because if you reduce the weight of the battery pack can also reduce a lot of costs.In addition, simulation mode, manufacturers can optimize the material, shape, such as a car in other sizes and materials, but also can be secondary weight loss.

JohnGerman introduced, according to US standards, predicted that by 2025 the car has a 7% weight loss.The latest example is a 2015 Ford F150 progress of weight on this nation's largest-selling models currently, 95% of the body is made of aluminum, 77% of high-strength steel frame is HSS,While achieving a reduction in the engine. Director (hereinafter referred to as automotive lightweight Union) Committee of Experts on automotive lightweight technology innovation strategic alliance Chen Yilong noted,Automotive lightweight is not simply equal to the use of lightweight materials, it is not simply a technical issue, China as a car producing countries, automotive lightweight material technology and knowledge must be managed from two perspectives.He talked about that, at the end of 2007, when the newly established automotive lightweight Union, China's passenger car business is not the lightweight design as a part of, then the level of domestic car lighter seriously lagging behind in development in the world.

"Automotive lightweight not simply weight loss, but to meet the functional requirements of the product and the product under controlled conditions to achieve weight loss products."Chen Yilong stressed that lightweight vehicles three technologies - design, materials, technology, three aspects of technology to integrate applications."Timber principle for lightweight vehicles, not who to say who is the best and lightest materials, the automotive sector there should be no such concept."The current international general two words are:" the right material in the right place, with the right technology in the right place. "

From 2159 to the existing automotive lightweight Union sedan with 777 SUV, light weight coefficient analysis we can see, China's passenger car weight loss should be more than 15%,that is to say to the entire passenger cars by 2020It should reduce the average curb weight of more than 15%.

JohnGerman has a similar view, he believes that all car manufacturers in weight loss measures to achieve compliance by quality, while achieving fuel efficiency and long-term development goals,For different manufacturers adopt different strategies, for high-strength steel, aluminum, plastics, fiber and manganese, are very much the use of materials, and eventually they will find their place in the next technological revolution among.

The underlying database

Let harmful substances into control

In this seminar, in addition to lightweight technology, a variety of other key automotive materials technology, automotive harmful substances, such topics as air quality inside the meeting also had a full exchange and discussion.Even this relatively particularity retardant material material will have a significant impact on the automotive manufacture and use. Director of China Society of flame retardant,China Fire Protection Association Professional Committee of electrical fire Du Haiying introduction,Car fire statistics from the United States occurred in 2012 can be seen, the car fires accounted for 13% of all fire deaths of 300 people, injured 800 persons, property damage reached $ 110 million, an average of less than three minutes in a car fire .

A Statistics show that plastics used inside a car can reach 105 kilograms, accounting for 9.3% of all the material, close to 10%, and this proportion is rising.There are three main types of polymer --PP (polypropylene), PU (polyurethane) and PS (polyvinyl chloride), which in all material inside the material with the most, accounting for 66%.Du Haiying analysis, fire vehicles continues to rise, there is a very important reason for this - the current application of plastic materials for automobile great deal of risk.DU Hai Ying pointed out that after extensive use of flammable plastic material, in order to meet fire safety standards must be flame retardant, the effect of flame-retardant materials used in some fire into the car and aviation has played a huge role.

For automotive production and use of the whole life cycle of hazardous substances problem, stripped of harmful substances is proposed based on the center green supply chain management solutions.Steam Centre believes that the main responsibility as the management of automobile production enterprises should attach great importance to long-term planning efforts to strengthen controls in the following areas:One is to build a sound management system to ensure ongoing compliance. Hazardous substances and recoverability rate management system, a clear job content and work processes of the responsible departments,In product planning, design, development, procurement, production, sale of the entire process management and control of hazardous substances added requirements, improve the monitoring and measurement measures to promote the continuous improvement of the management system, to ensure products consistently meet regulatory requirements.Second, the use of industry information platform, collecting data component material. Many auto parts materials and different target markets may have different limits for hazardous substances,   If all were harmful substances, expensive, huge workload, but on the whole industry supply chain, relying on industry information systems data collection materials vehicle parts,Can effectively achieve comprehensive, accurate and timely tracking and analysis of vehicle usage with international practices harmful substances and carry recoverability rate calculation, and reduce the burden on enterprises and meets.

Third, to fulfill the responsibility system and extend release "vehicle dismantling Guidebook."

The fourth is to strengthen the close cooperation of the whole industry chain, and improve industry as a whole "green" level.Automobile production enterprises should strengthen cooperation with suppliers, and promote the development of recycling and environmental protection and new materials better, to strengthen the alternative materials and technology to promote the application of recycled materials;Meanwhile, the establishment of close cooperation between the dismantling and recycling companies, recycling companies, Carried out jointly with the recyclable material vehicle determination, recycling technology, green dismantling technology, expanding the field of renewable recycled materials, improve the quality of recycled products, the formation of new green competitive advantages, and promote the whole industry chain of green car development .

Zhang Jianwei also said steam in the center of the automobile industry in promoting green and sustainable development has been done quite a lot of basic work,Including the implementation of and promote the management of hazardous substances cars, passenger cars accounted for using the average fuel consumption, automotive products and other eco-design projects commissioned by the government;Steam Centre organized auto industry-related companies set up a car with material working group of automotive hazardous materials management and common technology research alternative materials,Development and operation of Chinese automobile material data system CAMDS, China Green car dismantling systems CAGDS, automotive and other industries basic materials database AMASS underlying database, intended to assist China's automotive industry with total solutions with high efficiency and hazardous substances control, so as to enhance China's automobile level of environmental protection products.
